Tom has a mass of 66.2 kg and Sally has a mass of 51.5 kg. Tom and Sally are standing
17.2 m apart on a massless dance floor. Sally
looks up and she sees Tom. She feels an
attraction.
If the attraction is gravitation, find its mag-
nitude. Assume both can be replaced by point
masses and that the gravitational constant is
6.67259 x 10-11 N. m2/kg-.
Answer in units of N.

Find the steady-state temperature at the center of the plate = /2, = /2) for sums of w from n=1 to n=19 (only odd values). find the value of n for which the change in /2, /2) is less than 1% from the value at the previous n. at this point, we consider the solution converged. does the value of the temperature at the center seem reasonable? in this part, the values of x and y are constant scalar values. you should produce a plot of the value of n on the horizontal and the estimate of the temperature at the center of the plate on the vertical. b. using the value of n (or larger) that resulted in convergence in part (a), create a contourf plot of the temperature distribution across the entire plate. use enough spatial subdivisions to create a useful plot. comment on the results. hint: you need to determine what “x” and “y” values to use to make your t matrix. i recommend using a different number of x and y values. use enough x and y values so that the plot is “smooth”.
